ELECTRICAL INSTALLATION
The Australian installation shall be in accordance with The Plumbing Code of Australia (PCA).
This appliance should be connected to a hot water supply (Max 65°C ) for in accordance
with Australian Standard AS/NZS 3500.1. for optimum performance.
The water supply pressure should be a minimum 200 kPa at all times and flow rate should
be at least 10 litres per minute. A static pressure higher than 600 kPa (73.5 psi) requires a
pressure reducing valve upstream of the supply line. If water pressure is below 150 kPa,
the use of a rinse booster pump is recommended.
This appliance is designed to drain to a tundish. Waste connection to a spigot is not
recommended and may cause draining issues.
The drainpipe should withstand 70°C (158°F) in continuous duty conditions.
The grey water drain hose must have a fixed watertight seal above the tundish in
accordance with the Australian Standard AS/NZS 3500.2.

OPERATION
Machine start-up
Start-up
• Check if the pump suction filter is properly inserted in its seat in the wash-tank bottom
(see pict 2).
This filter must be cleaned every 20 wash-cycles or whenever necessary.
DO NOT use the appliance without the filter.
• Put the surface filters in place (see pict 2).
• Shut the dishwasher hood.
• Turn the water valve “open”.
• Turn the main power switch ON.
• The machine is on STAND-BY. In the Bdisplay, the message STAND-BY will appear.
• Turn the button C.
The machine start will be active when the Abutton will light in red and on the Bdisplay
the STAND-BY message will be off.
The water filling of the wash-tank is done by pre-heating via the boiler. On the Bdisplay,
the messages FILLING WATER and HEATING will alternate. Should the machines be
equipped with the WRAS certified Break Tank, the tank filling phase is extended.
The display will read HEATING, till wash-tank and boiler will reach the set temperatures.
During this process, the machine will not allow any cycle selection or start.
If the machine is in standard configuration, with hot water in-feed (50°C), with no extra
power, the Abutton will light in green after some 20 min.
Should the machine be equipped with integrated heat recovery system (see pict 3), must
be definitely supplied with cold water in-feed. In this case the Abutton will light in green
after some 45 min.
At the end, the Bdisplay will show the last used cycle.
Operation
• Insert the rack filled with dishes to wash. The plates must be correctly placed in the rack
(see par. Cutlery and crockery loading).
• Select the wanted washing cycle by pushing the green START button A; the display will

• Close the hood; the wash cycle starts automatically. The button "A" will light in blue. All
wash-time long the display will read the wash-tank temperature and the boiler temperature.
Below the temperatures indications line-bar is displayed to show the progression of the
wash-cycle.
When the wash-cycle ends, the partial draining of the washing water activates. After that,
the hot rinse cycle will take place. A blue/green flashing on the button A will indicate
the CYCLE ENDED.
By selecting the option SELECT CYCLE the wash-cycle will not start, when lowering the
hood. This function is meant to shut the hood without activating the wash-cycle, in order
to keep the machine closed and reduce cooling-down during stand-by periods.
NB: At cycle-end, keeping the hood closed, dishes will not dry. Take out the rack or keep
the hood open to allow evaporation, helping the drying of the dishes.
When opening the hood, the button Awill turn green, indicating that the machine is ready
for a new wash-cycle.
We recommend to change water at least twice a day, or whenever needed.
The machine is set to change all the wash-water automatically, every 300 cycles.
Switching OFF

Note the following recommendations:
• Crockery and cutlery should not be inserted inside one another, covering each other.
• Place the crockery in order to all surfaces can be reached by water; otherwise the dishes
are not washed.
• Make sure all the crockery are in a stable position and that the hollow containers don't
overturn (cups, glasses, bowls, etc.) .
• Place in the rack all the hollow containers such as cups, glass, etc. upside-down.
• Place the crockery with deep hollow with upper face downwards, so that water can flow
out.
• Make sure the smaller crockery do not fall from the rack.
• Check all the wash arms runs freely and they are not blocked by too tall or too prominent
crockery. Eventually, run a manual rotation of the arms to check it.
Some foods, such as carrots, tomatoes, and others, may contain some natural dyes sub-
stances, that in large amounts, can alter the crockery and plastic parts colors.
Any discoloration does not mean that the plastic is not heat resistant.
Crockery and cutlery not suitable for dishwasher
Not suitable for dishwasher:
• Wooden crockery and cutlery or with wooden parts; water at high temperature causes
deformation to wood. Also the adhesives used are not suitable for treatment in the
dishwasher; a consequence could be the handles detachment.
• Crafts, precious vases or decorated glasses.
• Not heat-resistant plastic crockery.
• Copper, brass, pewter or aluminum objects: they may become discolored or opaque.
• The decorations on glass, after a certain number of washes, can lose gloss.
• Fragile glasses or crystal items, if often washed, can become opaque.
We recommend to buy exclusively crockery and cutlery suitable for dishwashing.
After several washes, the glass can become opaque.
It is mandatory to repeat the washing cycle if at the end of the cycle the crockery
are not well clean or if there are washing residues (glasses, cups, bowls, etc. with
liquid inside).
Detergent use
The machine has a standard detergent dispenser. The machine automatically sucks the
product.
The detergent shall be the NO FOAM type, suitable for industrial dishwashers.
The detergent must be introduced in the tank. The use of good quality liquid detergents
is recommended. By request the dishwasher can be equipped with an electric detergent
dispenser (always recommended).
Follow the manufacturer’s recommendations for chemical dosage, related to the local water
hardness. 1cm. of the product drawn into the tube is equal to about 0.15 g. A correct amount
of detergent is very important for a successful wash.
Should the detergent lack, the display will show DETERGENT LEVEL (only with optional
"Sensor for Chemicals Low Level").

ECOLOGICAL ASPECTS
Recommendations for optimal use of energy, water and additives
Chemical dosing: A pre-set (by the manufacturer) quantity of chemical is injected in the
resins at each cycle.
Use the machine fully loaded when possible: This shall prevent detergent, rinse aid, water
and energy consumption waste.
Detergent and rinse-aids: Use detergents and rinse-aid chemicals with high biodegradability,
to best respect the environment. Verify proper dosage in relation to water hardness at least
once a year. Excess product pollutes rivers and seas while an insufficient dose results in
unsatisfactory dish washing and/or hygiene.
Boiler and Wash-Tank temperatures: The boiler and tank temperatures are set by the ma-
nufacturer in order to obtain the best washing results with detergents on the market. The
temperatures can be reset by the installer in relation to your detergent.
Pre-washing: Carefully pre-wash with a moderate amount of water at room temperature to
facilitate the removal of animal fats. To remove encrusted materials warm water soaking is
recommended.
Note: Wash objects as soon as possible to avoid deposits from drying and compromise
effective washing.
For effective washing routine dishwasher cleaning and maintenance is advised.

Disregarding the points listed above and of any the information contained in this
manual can cause energy, water and detergent waste with a subsequent increase in
running costs and/or performance reduction.
